方法调用:
导入jar包
复制以上CustomXWPFDocument类和WorderToNewWordUtils类到项目合适路径(根据自己项目情况判断)
主类调用方法说明(既以上Test测试类)
对于一般的字段替换,只需要保持(key,value)的键值对方式赋值替换即可,key和模板占位字符保持一致,例:
Map<String, Object> data = new HashMap<String, Object>();
data.put("date","−03−06");data.put("{date}", "-03-06"); data.put("date","−03−06");data.put("{name}", “东方明珠”);
data.put("address","华东院");data.put("{address}", "华东院"); data.put("address","华东院");data.put("{communityvalue}", “”);
data.put("safetycode","华东院");data.put("{safetycode}", "华东院"); data.put("safetycode","华东院");data.put("{picture2}", “”);
data.put("picture3","");data.put("{picture3}", ""); data.put("picture3","");data.put("{buildingvalue2}", “华东院”);
data.put("patrolPhoto1","");data.put("{patrolPhoto1}", ""); data.put("patrolPhoto1","");data.put("{patrolPhoto2}", “”);
data.put("${buildingvalue3}", “中国”);
如果需要插入图片,则需要重新创建一个Map集合存储图片数据:例
Map<String,Object> picture1 = new HashMap<String, Object>();
picture1.put(“width”, 100);
picture1.put(“height”, 150);
picture1.put(“type”, “jpg”);
picture1.put(“content”, WorderToNewWordUtils.inputStream2ByteArray(new FileInputStream(“D:/timg.jpg”), true));
data.put("${picture1}",picture1);
如果有多张图片,则需要创建多个Map保存图片,其中它的属性值应保持不变(如上:width,height,type,content),需要注意的是对于一般字段或者是图片最终都存储在data集合中,如下:
Map<String, Object> data = new HashMap<String, Object>();
对于需要根据具体数据动态生成的表格,我们将数据存储在一个List集合中,如:
//第一个动态生成的数据列表
List<String[]> list01 = new ArrayList<String[]>();
list01.add(new String[]{“A”,“11111111111”,“22”,“22”});
list01.add(new String[]{“A”,“22222222222”,“33”,“22”});
list01.add(new String[]{“B”,“33333333333”,“44”,“22”});
list01.add(new String[]{“C”,“44444444444”,“55”,“22”});
//第二个动态生成的数据列表
List<String[]> list02 = new ArrayList<String[]>();
list02.add(new String[]{“A”,“11111111111”,“22”,“22”});
list02.add(new String[]{“d”,“22222222222”,“33”,“22”});
list02.add(new String[]{“B”,“33333333333”,“44”,“22”});
list02.add(new String[]{“C”,“44444444444”,“55”,“22”});
如上是两个我们需要根据具体数据动态生成的表格,如list01中数据,当list中String数组的第一个字段相同时,则在创建动态表格时会将这两个单元格合并,其他列数值相同不影响合并。注意:这里的创建的String数组的列数应该和模板的表格列数保持一致。数据保存好之后将list数组统一保存在mapList中,如下:
List mapList = new ArrayList();
注意:
由于无法动态获取需要动态填充的表格,所以我们定义了一个静态数组保存需要动态生成的表格的位置,如下:
//需要动态改变表格的位置;第一个表格的位置为0
int[] placeList = {1,4};
如图1所示,从上至下表格所在位置分别是0-4;而我们需要动态生成的是第二个和第五个,故此处传参{1,4}
最后调用方法导出word即可;如下:
CustomXWPFDocument doc = WorderToNewWordUtils.changWord("C:/Users/user/Desktop/test1.docx",data,mapList,placeList);FileOutputStream fopts = new FileOutputStream("D:/呵呵.docx");doc.write(fopts);fopts.close();
在changeWord方法中,第一个参数是模板路径,第二个参数是填充数据,第三个参数是动态表格填充数据,第四个参数是动态表格位置;
友情提醒:(以下内容若需要可采纳,不需要可跳过)
使用poi生成Word会发生分段混乱的问题,例如:在操作POI替换word时发现getRuns将我们预设的${product}自动切换成了成了两个部分
${product } 或者 product既会出现空格分离字段的情况;建议使用从左往右的顺序进行模板字段填充(既:{ product } 既会出现空格分离字段的情况;建议使用从左往右的顺序进行模板字段填充(既:product既会出现空格分离字段的情况;建议使用从左往右的顺序进行模板字段填充(既:→{→product→} 而不是 $→{→}→product的方式);
亲测有效:使用notepad++的xml插件修改模板(保证解析完美)
(一) 安装notepad++并为其添加插件XML Tools插件(具体步骤自行百度)
(二) 将修改好的word模板另存为xml格式的文档;如下图所示
(三) 使用notepad++打开xml模板,刚开始打开是一个毫无逻辑可寻的文件,这时我们使用xml tools工具格式化xml文件:如下:
(四) 如上图可看出模板被解析成了多部分,此时我们修改文件,让其保持为一个字段:如下
(五) 保存文档之后用word打开xml文档,然后另存为所需要的docx格式word即可
